Overview

The INIU 45W Mini Portable Charger redefines what a 10,000mAh power bank can look like. Instead of the usual bulky brick, it offers an ultra-compact design that is approximately 45% smaller than standard 10k banks, fitting easily in a pocket or slim purse. It supports true fast charging up to 45W via USB-C PD and QC, capable of boosting an iPhone 17 Pro Max from 20% to 76% in just 30 minutes.

What Stands Out Most

The most distinctive feature is the thoughtfully designed detachable cable. Unlike fixed built-in cables that can ruin the entire unit if damaged, INIU's 0.4ft braided USB-C cable can be replaced if it wears out, extending the product's lifespan. This design choice also means you aren't tethered to a short, unmovable cord when charging multiple devices. Additionally, the charger's slim profile and lack of cable hunting make it a great travel essential for flights, road trips, and daily carry.

Performance and Speed

While many 10,000mAh packs struggle with newer fast-charging phones, this unit stands out with its 45W output. It supports Samsung Super Fast Charging, PD, and QC, allowing phones to charge at speeds comparable to wall outlets.

  • Single Port: Delivers full 45W when using one USB-C port.
  • Multi-Port: Drops to ~20W per USB-C port if both are used simultaneously; the USB-A port outputs 18W.
  • Tablet Power: Can charge an iPad Pro to 55% in 25 minutes and even handle a MacBook Air.

Design and Portability

The charger is barely bigger than a credit card or wallet, making it a discreet addition to your gear. It features two USB-C ports and one USB-A port, enabling multi-device power for phones, tablets, and other USB-C gadgets. The inclusion of a lanyard cable means you can attach it to a bag for instant access without worrying about forgetting a separate cable.

Who It's For

  • Travelers who need flight-safe, compact power without bulk.
  • Users with fast-charging iPhones (15–17 Pro) and Samsung S24/S26 phones.
  • Style-conscious buyers who want a charger that looks as good as it performs.

Who Should Skip

  • Users who need to charge three devices at full speed simultaneously (speed drops on multi-port use).
  • Those who require a built-in power brick to recharge the bank itself (you need your own USB-C brick).

Verdict

The INIU 45W Mini is a smart pick for anyone who values style and convenience alongside performance. Its detachable cable solves a common pain point of fixed-cable chargers, and its 40% smaller footprint ensures it never feels like a burden. While it requires an external brick for recharging, the trade-off for such a sleek, high-speed, and durable design is well worth it for daily users and travelers. [Check current details on Amazon]

Verdict

If you prioritize a sleek, compact design that doesn't sacrifice speed, the INIU 45W Mini is a smart pick. It charges modern iPhones and Samsung phones nearly as fast as a wall outlet while remaining barely bigger than a wallet, offering a premium feel at a value-oriented point. The detachable cable is a thoughtful upgrade over fixed-cable models that often fail when damaged, making this a reliable, long-term companion for flights and daily commutes.
